One more derivation of the Lorentz transformation
, 1976 After a criticism of the emphasis put on the invariance of the speed of light in standard derivations of the Lorentz transformation, another approach to special relativity is proposed.

Lorentz-conformal transformations in the plane
Expositiones Mathematicae, 2017 While conformal transformations of the plane preserve Laplace's equation, Lorentz-conformal mappings preserve the wave equation. We discover how simple geometric objects, such as quadrilaterals and pairs of crossing curves, are transformed under nonlinear Lorentz-conformal mappings.

Understanding the Growth and Properties of Sputter‐Deposited Phase‐Change Superlattice Films
Advanced Materials Interfaces, EarlyView.The study explores the sputter deposition of highly textured chalcogenide superlattice films for phase‐change memory applications. It examines the effects of temperature, pressure, and seeding layer on film growth, constructing a pseudo‐phase diagram to understand the effect of each growth parameter.

Gauge and Lorentz Transformation Placed on the Same Foundation
Advances in Mathematical Physics, 2011 We show that a “dynamical” interaction for arbitrary spin can be constructed in a straightforward way if gauge and Lorentz transformations are placed on the same foundation.

Advanced Materials Interfaces, EarlyView.This study explores the synthesis and properties of hafnium‐titanium oxide (HTO) alloys developed by low‐temperature atomic layer deposition (ALD) as selective contacts for crystalline silicon solar cells. X‐ray photoelectron spectroscopy (XPS), surface photovoltage (SPV), and ellipsometry are employed to estimate the band alignment at the c‐Si/HTO ...

Magnetic Actuation Under DC and AC Fields of Thermoplastic Polyurethane With Strontium Hexaferrite
Advanced Materials Technologies, EarlyView.Magnetic thermoplastic polyurethane composites with strontium hexaferrite (SrFe12O19) are produced through a solvent‐free melt‐mixing technique. These composites display a magnetomechanical actuation mechanism, being able to deform (bend and twist) through DC and AC magnetic fields, showcasing their potential as a promising material for the fabrication

Potential relativistic dispersion in material medium
Results in Physics, 2016 Lorentz space-time transformation has been applied to the phase factor of a plane electromagnetic wave in linear material medium. The derivation shows in the limiting case for v = c, the phase velocity converges to its monochromatic value implying no ...
